This 7" is called XXX and is from one of the 45s I picked up in France. From Le Comptoir Du Disque, in Montpellier, for five euros. If you're ever in the area you should check it out - they were friendly and helpful and had lots of records!
A quick Google search didn't reveal much at all about Dorian. Cool tune, tho. "Boite De Nuit" means "Nightclub." The flip side, "Frissons D'Autocars" is an instrumental that's not as groovy.
